CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. § 119(b) to ChineseApplication No. 201910403033.3, filed on May 15, 2019, the disclosure ofwhich is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

The present invention relates to the field of air conditioningtechnologies, and in particular, to an adaptive condensing device for adual-loop heat pipe air conditioner.

A condenser is a component of a refrigeration system, and can convertgas or vapor into liquid, and quickly transfer heat in pipes to air nearthe pipes. The entire process is a heat release process. V-shapedcondensers are common on the market, are generally air-cooled, andperform refrigeration by using forced convection air. Air is driven by afan and is forced to circulate and flows horizontally through a finnedtube to take away heat released by a refrigerant. Finned tubes on leftand right sides of the V-shaped condenser are connected through upperand lower gathering tubes. The vapor gathering tube is above the liquidgathering tube. The finned tubes on the two sides play a condensationrole together. An applicant applied for a Chinese patent with apublication number CN206439954U on Dec. 29, 2016, and disclosedDUAL-LOOP AIR CONDITIONER INTEGRATING WATER-COOLING AND HEAT PIPEAIR-COOLING FOR ROOM REFRIGERATION. When implementing the Chinesepatent, the applicant found that an indoor unit requires a compressorevaporator and a heat pipe evaporator, and an outdoor unit includes awater-cooled condenser and an air-cooled condenser. That is, to make acompressor perform refrigeration under a working condition and a heatpipe perform refrigeration under a working condition, two condensersneed to be configured, thereby resulting in many components, complicatedinstallation, a large floor area, and high costs.

One end of the heat pipe condensingheat exchange micro-channel is connected to the heat pipeline, and theother end is connected to the indoor unit.

When a compressor performs refrigeration under a working condition, thefan is started, the second electric shutter is closed, the firstelectric shutter is opened, a high-temperature and high-pressurerefrigerant enters the compressor condensing heat exchanger from theindoor unit through a copper tube, and cool air is driven by the fan topass through the first electric shutter to exchange heat with thecompressor condensing heat exchanger, and a low-temperature andlow-pressure refrigerant is then transported back to the indoor unitthrough the copper tube.

When a heat pipe performs refrigeration under a working condition, thefan is started, the first electric shutter is closed, the secondelectric shutter is opened, a high-temperature gaseous refrigerantenters the heat pipe condensing heat exchange micro-channel from theindoor unit through a copper tube, and cool air is driven by the fan topass through the second electric shutter to exchange heat with the heatpipe condensing heat exchange micro-channel, and a low-temperaturegaseous refrigerant is then transported back to the indoor unit throughthe copper tube.

The adaptive condensing device for a dual-loop heat pipe air conditionercan make the compressor the heat pipe perform refrigeration under theworking condition, and there is no need to configure two condensers,thereby reducing occupied space, facilitating installation andmaintenance, and reducing costs.

The present invention is further provided as follows: The compressorcondensing heat exchanger is located on a side of the first electricshutter close to an interior of the condenser body.

The present invention is further provided as follows: The heat pipecondensing heat exchange micro-channel is located on a side of thesecond electric shutter close to an interior of the condenser body.

The present invention is further provided as follows: The compressorcondensing heat exchanger is a copper-tube aluminum fin.

The present invention is further provided as follows: A cavity is formedinside the condenser body, and an air inlet of the fan is located in thecavity.

The present invention is further provided as follows: A section of thecondenser body is V-shaped.

The present invention has the following beneficial effects: When thecompressor performs refrigeration under the working condition, the fanis started, the second electric shutter is closed, and the firstelectric shutter is opened, and cool air is driven by the fan to passthrough the first electric shutter to exchange heat with the compressorcondensing heat exchanger. When the heat pipe performs refrigerationunder the working condition, the fan is started, the first electricshutter is closed, the second electric shutter is opened, and cool airis driven by the fan to pass through the second electric shutter toexchange heat with the heat pipe condensing heat exchange micro-channel.In this way, the adaptive condensing device for a dual-loop heat pipeair conditioner can make the compressor and the heat pipe performrefrigeration under the working condition, and there is no need toconfigure two condensers, thereby reducing occupied space, facilitatinginstallation and maintenance, and reducing costs.
